While a protection sheet 60 is disposed on a non-skin-surface 20a of an absorbent article 1, part of the protection sheet 60 is folded back in such a manner as to reach a position where the part overlaps other part, which comes in contact with the non-skin surface 20a of the absorbent article 1. An end portion 60a of the protection sheet 60 is bonded, while being folded back, to the protection sheet 60 by means of an adhesive material 70. Edge portions 60b and 60c on both sides of the protection sheet 60 in a longitudinal direction of the protection sheet 60 are bonded together through thermal fusion bonding while being folded. A second adhesive region 71 coated with the adhesive material 70 is formed in a predetermined position which faces the non-skin-surface 20a of a backsheet 20. The second adhesive region 71 is formed at a position corresponding to a non-adhesive region 52.
